Hello,

Round two of this overly-large series. Hopefully I've cleaned it up enough this
time around.

v1 can be found at:

  https://lists.ozlabs.org/pipermail/skiboot/2019-February/013226.html

Changes in v2:

* Drop the __attrconst patch that broke everything in snowpatch - it was a
  nice-to-have cleanup that turns out not to work everywhere.

* Cc: stable for all^Wmost of the things. I excluded patches 2-5 as they're
  build infrastructure-ish, but feel free to backport them too.

* Fix the race condition that I noted in patch 13/51 from v1. This actually
  turned into almost completely reworking ipmi_hiomap_handle_events(), but at
  least we have test cases covering that (now). The rework lead to actually
  *removing* code and generally making things simpler, and then also removing
  the tests associated with the removed code, and finally ending up with
  something that's (hopefully) more correct. I feel like that's a pretty good
  outcome.

* New patches in v2 include fixing header file change detection for make
  targets in libflash/test and the introduction of several new tests,

I've tested the series via:

1. Travis-CI: https://travis-ci.org/amboar/skiboot/builds/496338439
2. Done my own `git rebase -i --exec "make coverage" ...` over the series
3. run `make check` on the tip of the series to find any leaks, and
4. Done some manual verification of functionality and event handling on a
   Witherspoon (booting, and variously starting and stopping the BMC-side
   daemon while interacting with /dev/mtd0).

On the code coverage front, like v1 the series achieves 100% function coverage
of libflash/ipmi-hiomap.c and slightly greater than 90% line coverage.
  
Please review, if you can bear the tedium.

Andrew
